Blizzard has released (most) of the tier 9 models, both for Horde and Alliance. mmo-champion has a complete list of them, so it's worth popping over there for a gander. The post also lists all the set bonuses. I am of course only covering the paladin ones here.
First impressions? I'm not sure. I like the whole Blood Elf colour scheme thing Blizz has going on, but I'm not sure if it works with the models. Still, the shock of something that isn't yellow or pink has worn off and I think it's starting to grow on me. The more I think about it, the more I think it will probably look good. Throw in a cape, some boots, and voila. Yes, it's definately growing on me.
I must say though, I really like those shoulder spikes.
Overall: nice. I liked this straight from the get-go. It sort of looks paladin-like, and the colour scheme is reminiscent of tier 4 (remember that?). I took me ages to think why this armour is so fitting, and it finally came to me. As a kid, did you ever get stories read to you about knights in shining armour who would come to save the day and slay the bad guy? Well this is the kind of thing I imagined. It's very "I'm alliance and I'm here to save the day from the evil of the horde".
Actually, having said that I now like the Horde version a lot, lot more. I think it's from expressing it in that way. "I'm a weapon, and I will stop those who threaten my people". Speech is handy, isn't it?
This looks useful. The increased crit chance for judgements is very nice, especially a 5%. I'm usually quite worried about dropping crit for other stats on pieces of armour, but this would make me feel better. Of course, we'll have to see what sort of stats the gear ordinarily gives. As for the righteous vengeance crit chance, I'm not sure. This is one I'd actually have to see in the flesh to work out how useful it is.
Holy. The 10 second increased judgement time. At this point I will say that, although I used to be holy, it's been quite some time since I've done it "seriously", and I don't have much experience on the use of seals as a healer (I specced retribution before the seal changes). However, I'm pretty sure that the HoT healing increase is quite useful. It should see an increase of the use of sacred shield I should imagine.
As for protection, I have never tanked. Thus I am unsure as to how often Hand of Reckoning is used during combat. If it's used quite a bit then -2 seconds could be a nice little time saver. If it is hardly used in combat, then it's pretty useless. As for the divine protection cooldown reduction, I think that's pretty good. That should make it a lot easier on the healers and less stressful. (The divine protection bit has been edited, as I got my spells mixxed up. Thank you to Braundo on wow.com for spotting that!)
Overall, I think the tier is coming up rather nicely. The splitting between factions (for all tier 9 sets) is an interesting idea, and a brilliant one at that. It adds come flavour to the game and some much needed seperation between the factions, ever since we started chumming up in Burning Crusade. I'm quite looking forward to it.
(A big thanks to mmo-champion. The pictures are second-to-none.)
